i This invention relates :to the reception of messages by telephone, particularly messages in "Written form when the party called 'is An object of the invention is to provide: an arrangement'of apparatus and circuits which canbe utilized in combinationwith ordinary telephone circuits and instruments to enable the party calling to ascertain, firstthat the v message to be written down at the place party called is'not present at the opposite end or the line; and then by the'manipulation in a predetermined manner of the well-known dial for automatic telephones, to cause the called, to be kept till the party called returns. It is accordingly characteristic of this invention, that, after a normal connection is obtained, the mechanism of this apparatus, which may'beworked either mechanically or.

(ilectricallyfls set in motion throughfthe continuance of the operation ofthe dial Which must continue'as' the message istranscribed.

Theapparatuscan also be usedwhere there ,aie no' automatic telephones'fbut in such cases the callefls telephone apparatus must have a dial, ifihe desires to send such telephonic: written messages.

The-other objects and advantages of the invention are set forth in the following description, taken with the accompany ng drawings by which a form ofmy invention and the method of proceeding, are illustrated.

I donot, however, Wish to be limited to the details shownherein, as I may varythe arrangement withoutdeparting from the principle of the inventionor exoeeding'thesoope of the appended claims.

In practice thetelephonic writer of this invention contemplates the employme'nt of a so-call'ed Strov'vgenswitch, generally used in automatic telephones, mounted to move in 1 both a rotary and an axial direction. These movements are obtained by energizing a pair of magnets. After a letter has'b'een written, a circuit is closed through a'releasing magnet, and the rotary member or body 'ofthe' switch is returned to itsjorig'inal position.

The writing of Oneletter is thusefi'ected through thestrowger switch. When the body of the switch is mounted ona vertical axis, the body is lifted and turned to make thewriting, Figures 1 and 2 show the lift.

ing magnet H, the' turning magnet D f and the release-magnet A.

. "As d"s tinguisl1ed, however, fromthe usual 7 rent. These iinpllls figflre sent through the feede'relayf S321! (Figure 3) to the circuit of the [writing apparatus, ofv theicalled telephone instrument. At the first series of im pulses the drum Tr is lifted,atthe second series it is turned, It is, therefore, necessary to'sendtwo seriesof impulses'for' the Writing switch canmake ten vertical and ten horizontallstep's. It is, therefore, possible'to Write one hundred' letters,figures orsigns'. v p

Through the lifting -and turning of the drum the desiredletter gets into typing po-' of a letter. The body Tr of the Strowger 's'ition; That is, it'comesi oppositean inking Plbb QI l "Fb mounted to move as man: or-

ary typewriter, and in front of this ribbonthere pivoted s-trikinglever T7237 between'which and the "ribbon. F6 2. paper strip or,band-Pls fll'passes. .Whenth e lever .Th tis actuatedto strike theribbon andthe P 19 it P S S S' I QH gainst the dr um 'and V the letter, resting in typing position, is print ed on the paper band. After this the drum 7 is to be returned to its original position. At this instant the releaseanagnet A 1s ener ized, and lifts the retaining pawl or catch thus liberated and is turned back by a spring FLO also it drops by gravity against a rest As.

Starting position-is-thus regained;

At the first upward step of the drum the longer of a pair of spring contacts h, which is presseddown'iby the drum,'is freed, so'that the contact of the two springs takes place. At the return of'the drum against stop -As,the two springs separate. In the same manner the longer of two spring contacts 01 is moved at the first turning movement'of the drumto make contact with-the other. The end of this longer-springis received ina vertical groove or recess n i-n the side of the lmember Tr, when the latter isin starting position, asshqwn'in the description of. the switch. Bothpairs of contacts 7t and d are needed for theicontljol of certainrelays, as

will be lateri set forth herein. i

Figure 3 shows diagrammaticallythe circuits for supplying both parties with power, in connection with the switch of-the automatic contrivance for receiving telephonic .writtenmessages. [On this View the individual relays are marked with capital letters,

and the contacts thereof with the same small letters. M .The contacts are all shown in dead The two switch contacts fl iz' lf and KiIQ of the called subscriber T112 arein. center positiomlso that it is possible to receive incoming calls; Should,' how'ever, the subscriber T112 leave hisroom, he throws the switch arm to open'the contacts Kil and K112 so that histelephone apparatus is thus immediatelyconnected with the telephonic writer. An incoming call will therefore set the relay Xof the writingapparatus into operation said relay acting inn-supervisory capacity for theseveral operating relays included in the app'aratus.--I The circuit is-by way of the usual grounded battery and winding of'a feed relay to connecting wire 1, closed contact SW7, connecting wire 2, i. e. the connectingwire ofthe central'office to the called telephonesubscriber, openswitch contact K 21, connecting wire 3, relay X of the telephonic writer, connecting wire, 4L, contact '01, ground. Relay X is thus actuated and moves switch contact 001; The winding. 1 of the humming switch relay E is,thus actuated through a circuit com prlsingjrninus pole nearest to contact,w1, switched contact w1,"connecting; wire. 5, contact.c2 of the noft'yet live ,relay V, connecting wire 6, winding I ef the humming switch relay E, plus pole connected to'the'ot-her terminal-of this winding.

This relay E immediately brings its winding 11 into play. T he circuit here is from the plus pole adjacent contact W 1, through contact W1 of the not yet closed relay W, connecting wire 7 ,windingIIof the humming switch relay E, connecting wire 8, I switched contact 61. and minus-pole, adjacent this last-named contact. The called relay E then switches inthe winding I of the humming relay S; and a circuit is established from the plus pole at the left of relay S, winding 1 of the humming relay S, connecting wire 9, contact 81 of the humming relay, connecting wire 8, contact 61, and minus pole at 61. The humming relay is switched, but in the next moment disconnected, because the circuit of contact s1.is' broken. .This relayis now dead, but, in 'the'next moment alive again, then it is dead again, and alive, etc. The successive actuations of. this relaycauses vibrations, and these vibrations give rise to cause a humming tone, whichis inductively sent in anaudible wayto the calling, subscriber over winding II of the hummingfrelay in a single pole manner. The circuit is by way of ground, winding II of the humming relay S, wire connection 10, condenser C, wire connection 1 1, switch contacteQ ofthefswitched relay E, wire connectionj 8, open switch contact K21, wire, connection 2 to the calling subscriber,

Through the connection ofrelay X. the relay V also becomes alive, thecircuit being fromniinus pole adjacent contact 021, this switched contact 911, wire connection 5, relay V and plusjpolethereat, This relay has a copper, cylinder, therefore answering slower and will keep its contacts switched on even i the circuit should temporarily be bro- 1 ken. .Duringthe message relay V remains alive continuously. Contact 1)2 disconnects winding Pofgthe hun'nning switchrelay E, "which latterTremains alive over its winding II, at thesame time the switch contact '01 switches relay X uninterrupted from ground-ed pole, to the called subscribers wire. Relay X then has-its circuit as follows: grounded battery, Winding II of feed relay S792, wire connection 1, contact cpl, wire connection 2, open switch contact Kil, wire connection 3. relay X, Wire connection 4, switched contact v12, wire connection l2,--o'pen switch contact Kz'2, wire connection.13, winding 1 of feed relay 8792, ground.

The hummingrsound, audible to the caller, was his signal that the person called has; the telephonic writingcontrivance on his telephoneapparatus, but is absent; The'caller can then start writing the message. For every: letter, written in that; manner, two numerals are to be dialed. As, for example, for letter a the number 23. is first i V dialed. During the .return ,of the calling ace device to the normal position tw o -.interrupticnsnotthe circuitfare caused; This individnal feed relay ispl drops elf twice at the central office, and through; that sets contact- -Srl -=-in motion,'-at thesame time interrnptingjust as often :the circuit or relay X of the telephonic yvriterr The relay X; will t'allotl synchronouslyjnst often:

Therefore contact 901 .Will switch over as often as the interruptions? will occur "at the caller.-. Y Y c; .7 f With the first talli-ng oil of relay X; the

This relay W remains connected during-a series of impulses, after which falls elf. again. ith'the actuation" of relay W the Winding-II of the humming-switch relay is its contact 101. The relay E thenfalls ofi. Through that'thehulnming relay falls off too. The humming isthus at an end.

At the first series of inipulsesvthe'magnet H is energized With -everyactua'tion of the relay X. The circuit is from min-uspole at contact m1, this contact Wire connection 5,contact e02 oft-he delayed relay W,

At the. end ofthe firstimpulse series the ;relay W drops ofi', because the circuit is interrupted."

Contact st27of steer relayl St disconnects the winding of. the releasemagnet A from adjacent minuspole. Furthermore the circuit of the impulses is changed through contact st1:fro1n the magnetfI-l to theina-gnet D11- As soon as the subscriber Th1 proceeds to send the second seriesofi'mpulses, as'for example, Writing the second figure 3 for letter a,'-the'delayed falling-off relay W? is actuated if relay X drops oft"; Relay 021, this 'contact,swire connection a no-t yet switched relay T, wire:;connection ";-.l8",' sivitched contact h and plus; pole at At everyzactuation of relay X the connection 16; relay St, contact ttl of V magnet D therefore becomes alive through v a circuiteinbracing minus pole at contact tact @022 of switched relay W, Wirecon- ,necti-on l6,-contalct an of switched relay.St,, Wire connection 20; turnmagnet D;and the adjacent plus pole; At every p I actuation-of the magnet D,the drum T'r' lnaliesjra "horizontal step, because the lever Da,;.'inof\?es the cog Wheel Zr againstthe force eta-spring Rfdlwhich is coiled round th'c spindle a and regulates the horizontal returnfof thedrnin; The (lo-2,"S31 LlWaySX holds thed-ruin inlthe assumed-position.

Upon the first; horizontal moveinent of rotatiOn 'the ilong' spring of the pair d is atorced out from thever-tical groove N of the. drnin, and thus; the two contacts-are I caused :to engage.

'Withthat',the contactsh and'd are brought back to normal and thecircuit of the release magnet is interrupted. V The dialing of the next letter can now begin. v Theprocedure takes as little time as the dialing ofthe callingsubscriberfTnl.

At the end of the dialing, or, whenrthe calling subscriber is finished with writing,

he hangs up his receiver; andthe feedre'lay S721 drops off-permanently, and withit the relay X.) "The relay Wfisthen switched in thesameway as before. Right afterward the relalyVj drops 5 off.

Now the-paper band isfmo-v'ed one step further, making'a space in the written message, even if the calling subscriber has forgotten toindicate that after finishing his written message. Since the paper band-moves one step-=furtl1er,hefore the next letter of another message is writtenfthe space between the finished message and the first letter of the next message is therefore double.

Contact 126 switches release magnet A,

if the calling subscriber should hangup receiver' after having dialed but once. Thus a circuit iscreated in which the release magnet A lies as follows; plus pole H,

transfei' relay. The lever a turnsasmall type cylinder or wheel Tr. On the surface of the cylinder are the letters. At the first step, figured from normal position, a "spring of a pair-d is lifted from a groove 'n of type. wheel; At the proper timeythej type relay T is switched in, the same manner as described before. Its armature le'ver'be comes active, andpresses'the'type fork Tlv with the paper hand against 'color'ribbon Fb, against the type wheel and selected letter. Afterwards the release mag et A,

with that thetype wheel, through its return spring, is turned back to starting-point. The transmission of the paperband is inthesame manner as described before. l

. The active relay X, switching, transfenringzand switching as humming rsoun'd','takes I place in the same manner as shown in the description of' Figure 2." The same circuits areused for the switching of the relays V and W. i Y T The difference here" is that theimpuls series are not switched to liftingand turn ing ,magnets, but to a magnet turning only, and' one impulse series is sufficient jgfo'r the writing of a sign on-the'receiving contrivance. r
